CodeWarrior keeps giving PWM configuration errors

shouminliu — Tue, 15 Sep 2015 01:24:23 GMT

I set up a simple project for K10 and add a PWM component to it. No matter what I try, CodeWarrior keeps giving me configuration errors. Please refer to the attached image. The two red lines are the errors. Please let me know if you have any suggestions. Thank you.

Hi,

there is no problem to set 500ms period on my side. see attached project.

if this can not solve your problem, please send your demo project. thus we can know your problem on your specific project. thanks!

Have a great day,
Zhang Jun

Hello Jennie,

Thank you for the reference project. I could not figure out what was wrong with my project, so I deleted it and started all over again from scratch. This time it works. I can set the period and the duty cycle properly now.

I have another question though. Is there a way to use both the rising and falling edges of a PWM signal as interrupt sources? What I would like to do is to set up a GPIO and to use the rising and falling edges of a PWM signal to control the output level of that GPIO. For example, the rising edge of pin 44 (PWM) triggers an interrupt and the ISR drives pin 61 (GPIO) low. Conversely, the falling edge of pin 44 triggers another interrupt and the ISR drives pin 61 high. I only see a PWM_OnEnd event in CodeWarrior and am not quite sure if it is a rising edge interrupt or a falling edge interrupt. Could you please let me know if this achievable? If it is, how can I configure the components in CodeWarrior?

Thanks,

I'm using MC9S08AW16 and I'm starting with CodeWorrior 6.3. My doubt is: in the generated code "MCUint.inc" the compiler not include this file

I want a pratical example for this

thanks for attention
